[0022] The following describes in detail embodiments of the present application, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0023] The following describes the vehicle air conditioner wind direction adjustment method, device, vehicle and storage medium of the embodiment of the present application with reference to the accompanying drawings. In response to the problem mentioned in the above background technology that it is difficult for the vehicle air conditioner to accurately control the wind direction according to the user's needs, the present application provides a vehicle air conditioner wind direction adjustment method. In this method, by obtaining the user's finger pointing position, combining the user's voice command, and according to the current wind direction angle of the air conditioner, the target adjustment angle is determined, and the air conditioner is controlled to adjust the wind direction according to the target adjustment angle. In this way, the problem that the vehicle air conditioner is difficult to accurately control the wind direction according to the user's needs is solved, and the in-vehicle vision is fully utilized to achieve precise control, improve user experience, and reduce safety risks.

[0024] Specifically, Figure 1 A flow chart of a method for adjusting the wind direction of an on-board air conditioner provided in an embodiment of the present application.

[0025] like Figure 1 As shown, the vehicle air conditioner wind direction adjustment method includes the following steps:

[0026] In step S101 , an image of the position pointed by the user's finger is acquired.

[0027] Specifically, the embodiment of the present application can obtain an image of the position where the user's finger is pointing through the camera. For example, if the user's finger points to the leg, the camera obtains an image of the user's leg; if the user's finger points to the head, the camera obtains an image of the user's head.

[0028] It should be noted that before the user gives an indication of the air conditioner wind direction, the air conditioner wind direction angle is random. It can also be the angle before it was last turned off, or the user's habitual angle. No specific limitation is made here. When obtaining an image of the position where the user's finger is pointing, the current air conditioner wind direction angle can be recorded.

[0029] Optionally, in some embodiments, before acquiring the image of the position where the user's finger is pointing, the method further includes: calibrating multiple fixed points based on the user's body plane; and calibrating the positional relationship between the multiple fixed points and the viewing angle of the current image acquisition device.

[0030] It is understandable that due to the different body shapes and different seat adjustment positions of each person, the plane of the front surface of the body of the person in the car is different. Therefore, before use, it is necessary to calibrate two fixed positions in order to determine the plane of the body, and at the same time calibrate the position relationship between the fixed point and the camera angle of view, and record the angle of the air-conditioning wind direction at this time. Subsequently, according to the proportional relationship between the position actually pointed by the user in the angle of view and the correlation between the angle of the air outlet, precise adjustment can be made. Specifically, Figure 2 As shown in the figure, OP is the camera's viewing angle, A and B are the initial calibration points, from which the air outlet can calculate the required angle, and C is the position the user points when using it. It should be noted that the position needs to be recalibrated every time the seat is adjusted.

[0031] In step S102, the viewing angle position pointed by the finger is determined according to the image of the finger pointing position, and the first target adjustment angle is determined according to the viewing angle position and the current wind direction angle of the vehicle air conditioner.

[0032] Specifically, the in-car vision can identify various parts of the human body, and can also identify the position of the fingers. Therefore, the position of the finger on the plane where the face is located can be determined. When the user needs to adjust the air conditioning direction, he only needs to point his finger at a certain part of his body. After the camera recognizes the position, it can calculate the angle that the air conditioning needs to be adjusted based on the position information of the finger in the field of view and the angle of the air conditioning.

[0033] In step S103, the current wind direction angle is adjusted according to the first target adjustment angle so that the wind direction of the vehicle air conditioner blows toward the position pointed by the finger.

[0034] Specifically, after the vehicle obtains the first target adjustment angle, the current wind direction angle is adjusted. For example, the first target adjustment angle is +45 degrees in the up and down direction and -45 degrees in the left and right direction. The current wind direction angle is adjusted upward by 45 degrees and to the right by 45 degrees. The first target angle can also be 45 degrees to the upper right. The current direction can be directly adjusted to 45 degrees to the upper right. The specific adjustment method is not specifically limited here. Therefore, the user can adjust the angle according to the first target so that the wind direction of the car air conditioner blows towards the position pointed by the finger.

[0035] Optionally, in some embodiments, after determining the first target adjustment angle, the method further includes: receiving a user's voice instruction; determining a correction value of the first target adjustment angle based on the voice instruction; and correcting the first target adjustment angle according to the correction value.

[0036] Optionally, in some embodiments, based on voice instructions, a first target adjustment angle correction value is determined, including: parsing the voice instructions to determine the target blowing position of the vehicle air conditioner; determining the second target adjustment angle according to the target blowing position and the current wind direction angle of the vehicle air conditioner, and determining the correction value of the first target adjustment angle according to the second target adjustment angle and the first target adjustment angle.

[0037] During the actual implementation process, the finger may point to an approximate part, for example, the finger points to the shoulder. However, the user wants the air conditioner to blow to the left shoulder. At this time, the vehicle air conditioner can further adjust the wind direction according to the user's command to achieve precise control. Specifically, the embodiment of the present application can be combined with voice wake-up air conditioning adjustment. For example, the voice command is: hello + wake-up word + blowing direction position. It should be noted that the voice command can be customized by the user or pre-set and is not specifically limited here. The vehicle parses the voice command, determines the target blowing direction position of the vehicle air conditioner, and determines the second target adjustment angle according to the target blowing direction position and the current wind direction angle of the vehicle air conditioner, and determines the correction value of the first target adjustment angle according to the second target adjustment angle and the first target adjustment angle. For example, the user's finger points to the shoulder, and the user says "Hello, air conditioner, blow to the left shoulder". The vehicle parses the voice command and determines that the target blowing direction position of the vehicle air conditioner is the left shoulder. According to the target blowing direction position and the current wind direction angle, the second target adjustment angle is determined to be 45 degrees to the upper right, and according to the first target adjustment angle such as 45 degrees upward, the correction value of the first target adjustment angle is determined to be 45 degrees to the right.

[0038] The vehicle air conditioner wind direction adjustment method proposed in the embodiments of this application obtains the user's finger position, combines the user's voice command with the air conditioner's current wind direction angle, determines the target adjustment angle, and then controls the air conditioner to adjust the wind direction based on the target adjustment angle. This solves the problem of vehicle air conditioners having difficulty accurately controlling wind direction according to user needs, fully utilizes in-vehicle vision to achieve precise control, improves user experience, and reduces safety risks.

[0039] Next, the vehicle air-conditioning wind direction adjustment device proposed according to the embodiment of the present application will be described with reference to the accompanying drawings.

[0042] Among them, the acquisition module 100 is used to obtain an image of the position where the user's finger is pointing; the determination module 200 is used to determine the viewing angle position where the finger is pointing based on the image of the position where the finger is pointing, and determine the first target adjustment angle based on the viewing angle position and the current wind direction angle of the vehicle air conditioner; and the adjustment module 300 is used to adjust the current wind direction angle according to the first target adjustment angle so that the wind direction of the vehicle air conditioner blows toward the position where the finger is pointing.

[0043] Optionally, in some embodiments, after determining the first target adjustment angle, the determination module 200 further includes: a receiving unit for receiving a user's voice instruction; a determination unit for determining a first target adjustment angle correction value based on the voice instruction; and a correction unit for correcting the first target adjustment angle according to the correction value.

[0044] Optionally, in some embodiments, the determination unit is also used to: analyze voice commands to determine the target blowing position of the vehicle air conditioner; determine a second target adjustment angle based on the target blowing position and the current wind direction angle of the vehicle air conditioner, and determine a correction value of the first target adjustment angle based on the second target adjustment angle and the first target adjustment angle.

[0045] Optionally, in some embodiments, before acquiring the image of the position where the user's finger is pointing, the acquisition module 100 is further used to: calibrate multiple fixed points based on the user's body plane; and calibrate the positional relationship between the multiple fixed points and the viewing angle of the current image acquisition device.

[0046] It should be noted that the above explanation of the embodiment of the vehicle air conditioner wind direction adjustment method is also applicable to the vehicle air conditioner wind direction adjustment device of this embodiment, and will not be repeated here.
